INTRODUCTION TO THE LOMOND & THE NATIONAL PARK

ALAN BELL Ecologist, & The Trossachs National Park Authority.

The first part of this presentation is intended to help set the context for today’s conference, by providing some background on the National Park and the issues and activities in it. The second part will go on to look at some aspects of the Park’s ecology and issues relating to it. The Loch Lomond and The Trossachs National Park became the first to be designated in when it was established on 8th July 2002. The National Park is in close proximity to most of Scotland’s cities. , , , are all within a drive of one hour or so of it.

It covers 186,340 hectares (460,440 acres), extending from The on the peninsula to at the Eastern end of Loch Earn, and from Balloch to . The boundary extends to 350 km (220 miles). In broad terms the Park is comprised of the following four distinct areas:

Argyll Forest Breadalbane

The “ Forest” is centred around “Breadalbane” is centred on Strathfillan, and the of Clyde sea lochs, Glen Dochart and Glen, , Loch Goil and the Holy Loch. where the highest mountains are located. The area is extensively afforested, with At 1174m (3821 ft), Ben More is the the great majority of the woodland falling highest mountain in the park. within the Argyll Forest Park, owned and managed by the Forestry Commission Loch Lomond The Trossachs

Loch Lomond is the largest expanse of The Trossachs has numerous small to fresh water in Great Britain, with medium-sized lochs and intricate extensive oakwoods on its shores, many scenery. It includes and the islands and surrounding hills including popular tourist attraction, the “Sir Walter . Scott”. It also holds extensive areas of forestry, much of it in the Forestry Commission-owned Queen Elizabeth Forest Park. LAND OWNERSHIP AND LAND USE IN THE PARK

Significant parts of the National Park are in state ownership, especially by the Forestry Commission as well as Scottish Water, the Scottish Agricultural College and SNH. Other large areas are owned by public conservation charities the RSPB, National Trust for Scotland, Royal Scottish Forestry Society and Woodland Trust Scotland. The majority of the National Park is privately owned. The National Park Authority itself owns very little: mostly small parcels of land such as car parks and picnic areas at visitor facilities. In summary, 31% is publicly owned, 4.5% is owned by Charitable Conservation Organisations, 56% is in private ownership and 6.5% consists of water bodies. Housing The Park is home to a large number of people. The Park boundary runs through the middle of Balloch (below, right) in the at the north end of the greater Glasgow conurbation. (below, left) is the largest settlement in the Park, housing approximately 3000 people.

.

In total , there are 15,600 residents within the Park. The majority of people live in a few large settlements such as those already mentioned but low-density residential housing is widely dispersed throughout the area.. Leisure And Recreation

The area is highly accessible from the major centres of population within the Central Belt resulting in high levels of recreational use by day visitors, and well as having considerable national importance as a tourist destination. Some three million people live within about 1 hour’s travel of the Park. The development of infrastructure for visitors and the sheer numbers of people all have their impacts. The range of recreational activities brings about conflicting desires from different types of user. Fast, powered craft and quieter activities such as dinghy sailing or canoeing don’t co- exist easily. Transport

Two of the three trunk roads and one of the 2 railway lines from the central belt to the Highlands run through the Park. 85% of all visitors come to the Park by car. The majority of bulk freight is carried by road. In the eastern half of the Park, there are three significant dead end roads that attract their own difficulties of traffic management. Vehicle pressure on the roads tends to lead to engineering solutions to bring

improvements to traffic flow. Congestion on the A82 led to significant road works on west Loch Lomond side, with significant visual and landscape impacts.

The highly visible sections by Inverbeg and the Firkin cut shown below are extreme examples. However the trend continues.

. Water Supply The Park is also extremely important as a water supply, for hydro-electricity and drinking water.

. Loch Lomond and the reservoir complex at Lochs Katrine, Arklet and Finglas supply more than 1 million people, with 593 mega litres of water per day. Loch Sloy, Loch Venachar, Loch Arklet, and reservoir are all substantially enlarged or entirely created by dams. Even in Loch Lomond, water levels have been slightly raised by the construction of a barrage across the Rive Leven in Balloch. The Sloy hydro-electric scheme pictured above came into operation in 1950. Sloy is the largest conventional hydroelectric power station in the UK. It generates 152.5 MW with 4 turbines, giving it twice the capacity of Scottish Hydro-electric’s next most powerful conventional hydro-electric station at Errochty on the Tummel scheme. It can reach full load within 5 minutes of a standing start, making it ideal for use during times of peak demand. Farming A large proportion of the Park is used for farming, mostly livestock farming of cattle and sheep. Hill sheep are especially significant in both numbers and extent. In total there are 349 farms, covering 100,000 ha. 88,000 ha are rough grazing. About 4% of the local human population derive some income directly from farming. In 1993, the Park had 211,000 sheep and 14,700 cattle. In 2003 that had fallen to 165,000 sheep and 13,600 cattle. The economic conditions in farming such as the introduction of single farm payments can be expected to continue the trend towards further reductions of grazing in the high uplands and conversion of lower reaches into forest. Over time, these changes will have consequential impacts on vegetation type and thus scenic properties. Forestry The National Park has 50,452 ha of woodland, consisting of: · 34,307 ha conifer: mostly Sitka spruce- 80%, larch 8%, Norway spruce 5% · 7,568 ha broadleaf; mostly birch-38%, oak 21% · 5,550 ha open space in woodlands · 3,027 ha mixed, felled, coppiced or windblown woodland. Restructuring of the commercial plantations as the timber crops reach maturity is a major process on a truly industrial scale. Minerals The area has a long history of extraction of minerals for a variety of purposes. There are redundant quarries and mines for gold, lead and slate, with some conspicuous remnants such as the big slate quarries near and Aberfoyle. There are also operational sand & gravel quarries at Callander. The Tyndrum Gold mine pictured above is currently mothballed but could re-open, depending on the price of gold on the international markets.

Field Sports Angling for game , especially salmon and coarse fish, notably pike, as well as deer stalking are widespread in the Park. These are a significant income generator and employer in the smaller rural communities.

INTERNATIONAL CONTEXT The wide range of economic and other activities in the Park make it comparable in many ways to other National Parks in Britain. Its context internationally is also worth considering. Clearly this National Park is not largely uninhabited or a wilderness as might be the case in many other Parks worldwide. IUCN, the World Conservation Union defines six categories of “Protected Area”. I Strict reserve/ wilderness area II National park III Natural monument IV Habitat / species management area V Protected landscape/ seascape VI Managed resource protected area Category 2. “National Park” is defined as areas managed mainly for ecosystem protection and recreation. The selection criteria include that they should contain one or more entire ecosystems not materially altered by current human occupation or exploitation, and that ownership and management should normally be by the highest competent authority of the nation. Category 4 areas are defined as being managed mainly for conservation through management intervention, with ownership and management by the national government. Scotland’s National Nature Reserves fit partly into this category. Category 5 areas are managed mainly for landscape/seascape conservation and recreation. They should possess a landscape of high scenic quality with diverse associated habitats, flora and fauna along with manifestations of unique or traditional land use patterns as evidenced in human settlements and local customs, livelihoods and beliefs. The area should provide opportunities for public enjoyment through recreation and tourism within its normal lifestyle and economic activities. Category 6 areas are managed mainly for sustainable use of natural ecosystems. Selection criteria include that the area should be at least two thirds in a natural condition. The loch Lomond & The Trossachs National Park fits squarely into Category 5, as do the other UK National Parks. STATUTORY PURPOSE OF NATIONAL PARKS IN SCOTLAND The National Parks Scotland Act defines four aims that must all be delivered by National Parks in this country. In reverse order, these are: Aim 4 To promote sustainable economic and social development of the communities of the area Aim 3 To promote understanding and enjoyment of the special qualities of the area by the public, including enjoyment in the form of recreation Aim 2 To promote the sustainable use of the natural resources of the area Aim 1 To conserve and enhance the natural and cultural heritage of the area

Natural heritage is defined in the Act. It has three components: · Natural beauty and amenity · Geology and physiography · Flora and fauna

NATURAL BEAUTY AND AMENITY The National Park has a landscape of exceptional quality and diversity, which includes numerous large freshwater lochs, sea lochs, mountains forest and open ground, supporting a rich diversity of and animals. The Park is renowned for its scenic beauty, and three areas have been designated as National Scenic Areas (NSAs) - one covering almost the whole of the Loch Lomond basin and surrounding hills, another is the other in the core area of the Trossachs and a third the transition from lowland to at St. Fillans, Loch Earn. There is an exceptional variety of landscape types within the area, including : · Vast expanses of water,

· Rolling, relatively low-lying farmland on the more fertile soils along the southern margins of the Park,

· Policy parklands and designed landscapes around big houses such as Rossdhu.

· and the contrast between these managed landscapes and the wild upland landscapes further north and west.

· There is also a significant stretch of coastline, 62 km long, around the fjordic sea lochs in the south west.

GEOLOGY AND PHYSIOGRAPHY The National Park contains a wealth of geological features, including some of national and international importance. The that separates the Highlands from the Scottish Midland Valley across Scotland is the most well-known of these. Within the Park, the fault runs from Arden through , Aberfoyle and

Loch Venachar and its trace is clearly demonstrable within the islands of southern Loch Lomond. The diversity of the Park’s landscape derives from the effects of Highland Boundary Fault which divides the Park into two distinct regions with vastly differing soil types and topography. Famously much of the current land form was created by glacial action but land form continues to be a dynamic process. A major thunder storm in August 2004 caused significant land slips in Glen Ogle (below) and several other locations around the Park. Older scars from similar events can be seen on many other hillsides. FLORA AND FAUNA The flora of the Park ranges from the wide- spread and conspicuous features such as the bluebell-carpeted oakwoods to much less well known plants such as alpine bistort and purple saxifrage which are restricted to a few upland locations. Similarly the fauna ranges from widespread or familiar species such as badgers to much less well-known species like the freshwater peal mussel.

DESIGNATED SITES There are 61 Sites of Special Scientific Interest (SSSIs) within the Park area. Some of them are very large, like Ben Lomond, Ben More and Ben Vorlich.

Many SSSIs are also designated as Natura 2000 areas under European Directives. There are 8 Special Areas for Conservation (SACs) within the National Park, for the protection of rare, endangered or vulnerable natural habitats and species of wild plants and animals other than birds. and Meall na Samnha SACs are designated for their rare flora, including sub-arctic willow scrub. The Tay, Teith and are SACs for salmon and lampreys. These sites include several lochs and extensive stretches of riparian woodland as well as the rivers themselves. Loch Lomond Woods and Trossachs Woods SACs are designated for their Atlantic oakwoods. There is also one Special Protection Area (SPA) for wild birds; the Loch Lomond SPA which covers both the mouth of the Endrick Water with its overwintering Greenland white fronted geese and the Luss Islands with their population of capercaillie. Many of the species and habitats mentioned above are widespread throughout Scotland. What aspects of the Park’s biodiversity could be said to be truly distinctive?

LOCHS AND RIVERS The numerous lochs and rivers in the National Park together form a tremendous nature conservation resource. Loch Lomond, is the largest area of freshwater in Britain, covering an area of 71 square kilometres and is 36 kilometres in length. The northern end of Loch Lomond is extremely deep, at around 180 metres. Loch Lomond and Loch Eck are ‘unique sites’ in terms of the high diversity and unique combination of fish species present. There are nineteen species of freshwater fish in Loch Lomond including the largest of only two natural populations of Coregonus lavaretus in Scotland, the other being in Loch Eck. Loch Eck is the only Scottish site where arctic charr and powan co-exist and the only British site where they co-exist with Atlantic salmon and sea trout. Powan have also been introduced to Loch Sloy to try and protect the species and extend their range. The Trossachs lochs including Achray and Venachar, right, hold several populations of arctic charr though some of these seem to have disappeared in recent years. Also of particular note are the populations of lampreys. The presence of river, brook and sea lampreys is a qualifying feature for the Special Area for Conservation status under the Habitats Directive given to the and SACs. The Endrick mouth, right, is a real biodiversity hotspot. It is an SPA for overwintering geese, a Ramsar site as a wetland of international importance and a part of the Loch Lomond National Nature Reserve. It holds a wide range of wetland habitats and associated species such as the Loch Lomond dock, a whose distribution in the UK is restricted to a few sites around Loch Lomond, as well as large numbers of breeding and overwintering waders and wildfowl. The River Endrick, from its mouth at Loch Lomond up to , is also an SAC for its river and brook lampreys and Atlantic salmon. Its river lampreys are unique in the UK in that they don’t migrate to estuarine water to feed as adults but instead feed on powan and other fish in Loch Lomond. Other significant wetlands are found in , around Loch Eck and the north end of Loch Lomond. WOODLAND AND FOREST The Park has over 50,000 hectares of woodland and forest. The majority consists of productive commercial plantations, largely comprised of introduced coniferous species. Crucially the Park also has a very extensive native woodland resource. The relationship between the two is illustrated in the following maps of coniferous woodland and ancient and long-established woodland.

Ancient woodland sites which were recorded as being semi-natural on the oldest maps (either the Roy maps form 1750 or the first edition from 1860), and have been continuously wooded since then, form 8.5% of the woodland cover of the National Park area. A significant proportion is underplanted with conifers but that is being steadily removed as restructuring of productive forests takes place. Very significant broadleaf woodland expansion is underway, particularly on east Loch Lomondside and at Glen Finglas, but also via the widespread development of a forest habitat network embedded into Forestry Commission plantations, particularly along riparian corridors. Extensive felling on the east shore of Loch Lomond: for conversion to broadleaved woodland can be seen below. The Loch Lomond SPA includes the Luss Islands with their small remnant population of breeding capercaillie (right). The hope is that these birds will benefit from much of the woodland restructuring and improved woodland management now underway. The scale of the Forestry Commission ownership, plus land under other owners sympathetic to nature conservation objectives means that a truly enormous native woodland resource is deliverable in the Park, while still allowing for very significant commercial timber production. Oak Woodland The Atlantic oakwoods on both sides of Loch Lomond are a candidate Special Area for Conservation (SAC) and are home to summer visitors such as redstarts, pied flycatchers and wood warblers. Oak is the second most common broadleaf tree species as a result of its favoured status from the 17th to 19th Centuries. The Park contains an exceptionally diverse and extensive area of Atlantic oakwoods, representing a significant proportion of the Scottish total. The Loch Lomond Oakwoods form one of the largest areas of semi-natural woodlands in Britain.

Wet woodlands with trees emerging from seasonally inundated land are a feature in several locations around the Park

Pinewoods The important remnants of ancient Caledonian pinewoods at Glen Falloch (below left) and Strath Fillan (below right) are perhaps the most ‘natural’ of the woodland types, though these suffer from a severe lack of regeneration due to past grazing pressures. These remnants are the most southerly surviving natural pinewoods in the UK. They occur very close to the natural transition point from pinewoods to oakwoods as the predominant forest type. The area of ancient native pinewoods is small (67 hectares), but there are several new native pinewood schemes now in place that will help in the long term to expand and reconnect this woodland type over much of its former range.

UPLAND AND MONTANE HABITATS The occurrence of significant outcrops of limestone geology on the Breadalbane mountains create unusual alpine plant communities such as base-rich flushes and species rich tall herb communities that are rare in the rest of the Highlands.

The mountain massifs and upland areas of the Park contain remnants of heather moorland and montane scrub, and support a wide variety of species including golden eagle, peregrine, merlin, ptarmigan, twit, golden plover and, on some of the high tops, dotterel. The montane grasslands in the north of the Park are the main UK stronghold for the mountain ringlet butterfly.

The steep slopes with knolls, craggy gullies and cliff faces support many rare mosses, liverworts and lichens and extensive areas of snow-bed vegetation. Heaths, montane grasslands (many derived from heathland) and flushes have developed on the steeper slopes. GRAZING MANAGEMENT Perhaps the most significant issue in relation to both woodland and upland habitat management is that of grazing management.

There are a large number of red deer in the Park. Based in the most up to deer group date counts from 2000 and 2002, their total number in the Park is very approximately 10,000 individuals. This is probably a very high number in historic terms. The park also holds approximately 165,000 sheep, the great majority of which are hill sheep.

More integrated control of deer numbers and a reduction in hill sheep have the potential to yield significant biodiversity benefits. In particular, if the practical difficulties can be overcome, there is the potential to reduce grazing pressure in some areas sufficiently to allow reductions in the extent of deer fencing around woodlands. This would allow a scrubby upper woodland edge to develop and form a more natural transition between woodland and open ground habitats with benefits for many species. Conversely, there is a danger that changes to agricultural support under CAP reform may lead to unpredictable effects such as abandonment of upland farming. Whilst this could yield benefits for some habitats like heather moorland or montane scrub species such as willows and juniper that favour lower grazing pressure, it may be less good for some birds such as ring ouzel and certain butterflies that favour shorter vegetation. A task for the Park will be to attempt to steer the effects, be they ecological, landscape or socio-economic, of such changes.
